FIELD: sound reproduction in electroacoustic transducers. SUBSTANCE: proposed method involves use of digital coding from sound record or from sound medium which is copied followed by formatting and multiple reproduction of original sample. Device used for formatting digital signal receives reference sample from digital decoder and then copies these data by means of adjustable independent samplers controlled by common synchronizing generator. EFFECT: provision for controlling uncontrolled mechanical displacement of electroacoustic transducer membrane. 12 cl, 5 dwg |
